Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Upgrade torvalds/linux to version 6.18.39, 7.1.4 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds in the sriov_restore_vf_rebar_state process. An attacker can cause a host kernel panic or service loss by triggering a device state where configuration reads return error responses, leading to an out-of-bounds access in the barsz array during PCI state restoration. This is only exploitable if a device becomes PCI-inaccessible, such as during a failed power state transition, causing configuration reads to return error values.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
